My choice of the TH-700R4 is for the first gear being low to lower the resistance load on the engine as it now has 171,000 miles on it.

I also like the overdrive ratio being at .70 compared to the 2004R's .67 for the same reason.

Also, there is the little fact that when changing from the th-350 to either of the OD's the speedo drive and driven gears are more easily changed in the 700, the tailshaft housing on the 2004R is NON-removeable.

Both will necessitate the proper setting of the TV cable, and torque convertor lock-up in OD for longevity.
